A die-cut, boxing-style concert poster for a 1967 concert by Muddy Waters and Big Mama Thornton at the University of California, Davis. This cardboard beauty features a photograph by the legendary Jim Marshall, and is the only die-cut cardboard poster we’ve ever seen. Very rare and very beautiful. In excellent condition, measuring 12.5″ x 20.” Clear tape reinforcing the bottom corners, but as you can see from the scans, virtually invisible.
